She may be royalty, but today Queen Rania of Jordan's foremost duty was that of proud mother as she arrived at Sandhurst to see her son's passing out parade.

Crown Prince Hussein, 23, is the eldest child of Rania and her husband King Abdullah and has just completed his officer training at the prestigious military academy in Surrey.

Mother - Excitement - Photo - Son - Uniform

And his mother shared her excitement by poting a photo of her son in military uniform aged around four to Instagram, saying: 'As I look at this photo from 1998 I am thrilled about seeing you graduate from Sandhurst Military Academy tomorrow, God willing.'

Rania was certainly sure to stand out from the crowds in a vivid red broacde coat with a waterfall hemline, worn over a white dress, as she accompanied her husband King Abdullah who represented Queen Elizabeth by inspecting the parade.

Rania - Ensemble - Scarlet - Pumps - Handbag

Mother-of-four Rania, 46, teamed the ensemble with scarlet pumps and toted a black quilted handbag for the occasion.

The Jordanians were not the only royals in attendance at today's event which sees 96 officer cadets from the UK and 33 from abroad graduate.
